HOLLOW - very difficult burr puzzle

Discover Hollow – a sophisticated wooden puzzle for those looking for a real challenge for their mind and hands. Designed by Alfons Eyckmans and crafted with the utmost care by Pelikan Puzzles, this model impresses with its unusual design: six interlocking boards surround an empty core, forming an open structure made entirely of fine acacia wood. Hollow is visually striking—a delicate, almost sculptural object that makes for an eye-catching display piece on any shelf.

Your task: Separate all six boards and then reassemble the original puzzle. It sounds doable, but only at first glance. Even though the open construction reveals the interlocking connections, taking the puzzle apart completely remains a demanding spatial challenge. It requires careful observation and logical thinking.

Compared to a classic stick-burr, Hollow offers a unique playing experience. The precisely fitted boards require careful handling—and anyone who thinks the job is done once it's taken apart is mistaken: reassembling the puzzle from its individual pieces is a particularly difficult second task that once again demands true puzzle-solving spirit.

This makes Hollow an excellent choice for experienced puzzle enthusiasts who are passionate about the variety of burr constructions and want to add an extraordinary piece to their collection. Recognizing the relationships between the boards makes the puzzle exciting to study, while taking it apart and rebuilding it offers plenty to master. A puzzle that will keep you engaged for a long time—and is guaranteed not to disappear onto the shelf after the first attempt.
